"Madame Vastra, the fabled Lizard Woman of Paternoster Row, knew death in many shapes and forms. But perhaps one of the most bizarre of these was death by snow...
On a cold day in December, two young boys, tired of sweeping snow from the workhouse yard, decide to build a snowman - and are confronted with a strange and grisly mystery. In horrified fascination, they watch as their snowman begins to bleed...
The search for answers to this impossible event will plunge Harry into the most hazardous - and exhilarating - adventure of his life. He will encounter a hideous troll. He will dine with a mysterious parlour maid. And he will help the Great Detective, Madame Vastra, save the world from the terrifying Devil in the Smoke."
So this is another one of the short stories that came out alongside Summer Falls and The Angel's Kiss, and I have to say it is probably the best of the 3 of them. It has quite a gripping storyline, and despite being short, it is actually very good. If I would recommend reading any one of the three of these e-books that came out, it would definitely be this one.
